Abstract: This work proposes an intuitive fluid flow initialization for computer graphics applications. A combination of sketching techniques and Gradient Vector Flow is proposed to obtain a smooth initialization for the simulation using a Lattice Boltzmann Method (LBM). The LBM is based on the fundamental idea of constructing simplified kinetic models, which incorporates the essential physics of microscopic processes so that the macroscopic averaged properties satisfy macroscopic equations. The application of sketching techniques is proposed in order to enable the user to draw freely the initial state of the fluid flow using an intuitive interface. Moreover, it will be possible for the user to define multiply connected domains with suitable boundary conditions.
